...linical patterns and even death of patients. The paradox is that even though malaria by P. vivax has large global disease burden, this is a poorly studied disease, which has been long forgotten. Consequently, this new research programme has a large importance, and an estimated initial duration of 4 years...

...ogen-responsive tumors.) "The resolution of this paradox may lie in the timing of estrogen administration," Helferich said. Exposure to genistein, an estrogen, before puberty causes mammary gland differentiation. "A differentiated cell undergoes less proliferation and therefore is less likely to progress t...

..." A confusing aspect of hotspot origination, the paradox considers how hotspot locations are tagged. Previo...d with about 10 percent of hotspots in humans. The paradox arises from the idea that if the "tag" or motif lies too close to the hotspot, the tag is likely to ...

...Mental Health (NIMH) have discovered. The seeming paradox emerged from the first study to explore the effects of variation in the human gene for a brain master switch, DARPP-32. The researchers identified a common version of the gene and showed how it impacts the way two key brain regions exchange inform...

...fe," continues Dr. Finn, "so it seems a surprising paradox that fishes that live in water should have a problem acquiring it. Yet it was this paradox that provided the trail of clues for us to follow". "The physiological problems of reverting from ...

... the large-scale forest." In order to address the paradox of how so many rainforest species can coexist while competing for the same resources, Plotkin and Seidler studied a 50-hectare (500 meters by 1,000 meters) plot of lowland tropical forest at Pasoh Forest Reserve in peninsular Malaysia. They analyzed ...

...hropogenic Allee effect" in rare species through a paradox of value. When rarity acquires value, prices for scarce species can skyrocket, even though continued exploitation will precipitate extinction. And as long as someone will pay any price for the rarest of the rare, market price will cover (and exceed) ...

... of Clinical Investigation now sheds light on this paradox by showing that EP4 is required for one of the processes that must occur for the DA to close. Susumu Minamisawa and colleagues from Yokohama University, Japan, used several different approaches to show that in mice, EP4 signals are required for the ...

...in people with autism. This theory helps explain a paradox of autism: Some people with autism have normal or even superior skills in some areas, while many other types of thinking are disordered. Last summer, Just led a team of researchers that found for the first time that the abnormality in synchronizat...

...rs could be prevented. "Our findings point out a paradox in pregnancy," said Palmer. "Why doesn't the mother's immune system reject her fetus when it inherits a copy of the HLA gene from the father that substantially differs from hers? "It seems pretty clear that it's a good thing for the HLA genes of a...

...sche Universitt Mnchen believe the solution to the paradox could be a network of neurons in the snakes' brains a kind of snake brain firmware - that provides image enhancement as though the snakes were wearing virtual corrective lenses. Because snakes' brains are small, the physicists kept their model of an ...

... cooperation evolve in a cheater's world? It's a paradox called the "tragedy of the commons," a conflict between individual interests and the common good that has stumped scientists for generations. Now a trio of researchers, including a Brown University biologist, has created a unique theoretical model th...

A scientific paradox linking artificial sweeteners such as saccharin with a sensory experience in which plain water takes on a sweet taste has guided researchers to an increased understanding of how humans detect sweet taste. Reporting in an advance online publication ...

... allele was the risk allele. "The answer to this paradox may lie in the relationship between anxiety and drinking patterns," she said. "In societies where regular, daily drinking is the norm, such as in Europe, anxious Met individuals may be more vulnerable to alcoholism through using alcohol as a coping ...

...nearly 20 percent between 2000 and 2004. "The big paradox is that the computer science revolution is just unfolding," Chazelle said. "Why, then, are students are running away from it; why is there this decline when the field has never been more exciting?" Chazelle will be on the "Computer Science Behind You...

... is puzzling, however, Simms said. "Mutualism is a paradox because natural selection acts on individuals, so why would an individual do something costly that benefits another individual?" she said. "Such a system is also vulnerable to exploitation - one species taking advantage of another. What mechanisms co...

... tumor cells--but it also represents an intriguing paradox when it comes to the broader roles this protein plays in our well being. Past work has shown that in animal models, hyperactivation of the p53 protein is beneficial in terms of bestowing extra protection against tumor formation, but at the same time ...

... females." Dulac says this finding helps explain a paradox in humans, which lack functional vomeronasal systems. All vomeronasal-related mouse genes are inactive in humans, but this may not matter if pheromones can be sensed by the nose in humans as in mice. The exact nature of vomeronasal input to the hypot...

...r. To achieve this, cells need to overcome a major paradox -- the transfer of information, nutrients and waste products across fatty cell membranes which are designed to limit the transfer of these important molecules in order to keep the cell's environment separate from that of its neighbours. He will say t...

...in humans as well. In an effort to resolve the paradox and to help researchers more easily locate critical segments along the vast stretches of DNA deserts, scientists from LLNL, LBNL, and the Pennsylvania State University developed computational tools to decipher gene regulation by comparing the genomes...
